To all whom t may concern.'

Be it known that l, EMIL iii-iras, a citizen of the SwissConfederation,,residing at 1vllangen, Canton Zurich, witzcrlzlind, haveinvented certain new and useful improve ments in and Applicable toMachines ior Attaching` Heels to Boots and Shoes, of which the followingis a specication.

The present invention relates to improve` ments in and applicable tomachines used for attaching heels to boots and shoes from the inside or"the same. and has for its object the construction ot a heel nailingappliance by which all the nails for a heel may be driven insimultaneously at the same or dilerent inclinations to the heel and toeach other, whereby the heel and its pieces are held together and to theboot or shoe by inclined nails which may be inc"ned by relation to theouter shape ci the heel.

The object or the invention is to provide an appliance ci the lrinddescribed which may be easily inserted in the boot or shoe, withoutdistorting its shape and a 'further object of the invention consists informing; applianceV or nail bloclr its constituent parts in such amanner that the nails may be driven in the heels at the very peripherythereof thus securing' a goed and rin connection of the parts.

The invention farther consists of details of construction, whichtogether with the iteatures first mentioned, will be better understoodby reference to the drawings, in which Fig. l is a Sectional elevationoi the nail bloclr together with part ot a boot with heel to beattached.

Fig. 2 is a section talren on line A-B or Fig. 1 the boot being shown indotted lines.

Figs. 3 and i are cross-sections on lines (l-D and E-F of Figs. 2 and lrespectively viewed in the direction of the arrows.

Fig. 5 is a top view of the nail block.

llhe nail block according to the construc- `tion shown in the drawingsby way of an example comprises a rod l carrying a head 2. The latter iscomposed of three superposed pieces iirmly iiXed together. rlhe head 2has seven holes 3 each adapted to receive a nail 6 and a iiexible naildriver 7. All the drivers 7 are fastened on a slide 8 which is slidablymounted on the rod l. To

serial no. scarsa guide the slide 8 a in l0 is provided on the head 2projectinginto a bore 1l of the slide 8. r.the slide 8 is moved up anddown by any suitable device not shown in the drawing and a sleeve l2 isfastened to the head 2 overbridging the gap between the head 2 and theslide S. Each driver 7 consists oi a closely wound steel wire andloosely fits tl e bore 3 in such manner that it may move in said borewithout undue friction. Each bore 3 consists of three parts set atangles to each other, each part is straight and the length of theuppermost part 3 is equal to or greater than the length of a nail 6 tobe driven in theheel it or' the boot 5. rlhe angles at which the bores3ZL are drilled are varied according to the inclination desired to begiven to the nail to be driven such inclination being` determined by theshape of the heel. lt will be seen from drawings that owingv to theparticular shape of the head 2 and of the bores 3 in it and by theemployment of the flexible drivers '7 the head 2 may be placed wellwithin the hind end of the boot and nails be driven in the heel `fromvery near the hind Vend of the heel tlnis giving the istier i., goedhold and formingv a close joint.

When the nail bloclr is being used the slide S is lowered and therewiththe drivers 7 so that the nails 6 can be placed in the bores la oi thehead 2. rlhe boot 5 and the heel l to be attached are placed in positionon the nail block and the whole is moved under the cross-head of themachine. The slide 8 is moved upwards in the direction oi.5 the arrow lwhereby the nails are forced ont ol the head 2 into the heel d by thedrivers 7.

The number, position and inclination ci the holes may be variedaccording to the requirements of the heel and ot they shape thereof.

l/"Vhile l have described what l believe to be the best mode of carryingmy invention into commercial use, l do not confine myself to thedetails, as they may be modified without departing from the spirit ofthe invention.

Having now described my invention, what l claim as new, and desire tosecure by Letters latent, is-

A machine by which all nails for attaching a heel. to a boot may besimultaneously driven into the heel aty angles to each other 011 whichthe said drivers are mounted subzmd o the heel Comprising' incombination stentially as` described. l V Vd head having a plurality ofbores, the Yparts In testimony whereof I afix my signature of each borebeing` at an angle to each other, in presence of two Witnesses.
